A box of jello has a mass of 250 g. How many boxes must be bought to have 1 Kg of jello? *
Igoryamba

Answer:

4

Explanation:

According to the question, one box of jello has a mass of 250grams.

The question wants us to find how many boxes of jello would collectively weigh 1kg.

Since the units of weight here are in grams (g) and kilograms (kg), we need to convert to the same unit

1kilogram (kg) is equal to 100 grams (g).

Hence, if 1 box of jello weighs 250g

1000g of jello box will be 1000/250 in number

1000 ÷ 250 = 4.

Hence, 4 boxes of jello will weigh 1000g or 1kg.
